Patch 1.0.18

Hi everyone! This is a pretty big patch that we've been preparing for a few months. As you can see, game development doesn't end after release =). I actually like that the game keeps changing, it seems like a game about mutations should mutate periodically too.

Graphic improvements: - All hands in animations/illustrations redrawn in common style (hand taking mollusc/livewire/insectampule, burnt hand); - Almost all ampules were redrawn (Pod, Spiky, Holed, Shell, Trilobite); - New cerberus images (new portrait, new scene objects at the mushroom and spine levels); - New tortoise portrait.

Bug fixes: - Bioport image resets to default after loading savegame if bioport wasn't modified; - Adem activates hollow only near it.
